By sandwiching the raw EVOH resin shield between two high-performance adhesive layers and structural PEX-a or PEX-b layers, we ensure the delicate gas barrier remains completely protected against mechanical abrasions, jobsite installation friction, and direct physical impacts.
Utilizing high-degree thermal peroxide peroxide (PEX-a) or silane (PEX-b) cross-linking procedures, our pipes achieve a molecular network density exceeding 70-83%. This provides remarkable thermal memory, flexibility, creep resistance, and high-pressure stress endurance.
Our systems easily exceed the strict gas permeation limit established by DIN 4726. The EVOH barrier restricts oxygen diffusion to < 0.32 mg/(m²·d) at 40°C, virtually eliminating the risk of internal corrosion on expensive metallic system components, boilers, and heat exchangers.
Ningbo Minde Building Materials Co., LTD., located in the prominent Zhejiang industrial sector of China, is a vertically integrated, state-of-the-art facility specializing in high-performance polymer extrusion and injection-molded components.
With more than 20 years of processing experience in precision plastics engineering, we produce robust water supply systems, residential and industrial floor heating arrays, and agricultural distribution lines. To ensure maximum safety and environmental compliance, we utilize only premium-grade, imported raw materials from world-renowned petrochemical producers.
Our manufacturing complex is built upon 90,000+ square meters of highly automated space. It features three separate checkpoints for raw material verification, real-time in-process line calibration, and complete physical testing of finished products to guarantee a 100% pass rate before shipment.
Fully approved for EU installation
Tested for UK & Russian standards
Operating under a strict Zero-Defect quality philosophy, Ningbo Minde exports high-performance pipes and connections to over 50 countries, including Russia, Ukraine, South America, the Middle East, and Southeast Asia.
Our complete product line is subjected to strict structural testing at three operational levels: inbound polymer identification, online pressure stabilization checks during extrusion, and final destruction pressure tests of randomly sampled pieces.
Minde’s management systems and manufacturing processes are validated by international authorities. We hold current certification for ISO 9001:2022, ISO 14001, CE, British WRAS, and Russian GOST standards. This facilitates seamless customs clearances and ensures complete compliance with local building codes worldwide.
Our 5-layer co-extrusion technology is designed to exceed EN ISO 15875 requirements. Review standard product line technical dimensions, tolerances, and operational thermal limits below.
